Ok serious SPOT question to hijack the thread.

My wife works for a government agency and has to go out to check worksites, often on snowy backroads, in the winter, in areas where cell phone reception is spotty.

There is a system to call in to a service company who are supposed to alert the office if somebody hasn't checked in for a certain time. There is also an unofficial call in to the duty team leader. Last week they had an incident where somebody almost came off the road in an area with no cell coverage.

I was going to suggest they get a SPOT for the truck.
As I understand it they can send a check-in OK message, send a local/low priority help message to the office and if all else fails call the cavalry?

For this application it seems more flexible than a ELB, and cheaper and easier to use than a satphone. And the price is low enough to slip under the radar without needing the congressional committee needed to decide to do anything in this business.
